'To all-whom z'tmay concern.' y

Be it known that I, FREDERICK-O. BALL, va citizen of the United States,residin at Detroit, in the county 'of-Wayne and tate of Michigan, haveinvented newv and useful Improvements in Measuring Devices, of which thefollowing is'a specification.

y This invention relates to measuringd'evices and consists in certainimprovements in the construction thereof as will be hereinafter fullydescribed and pointed out in the claims.

The measuring device is particularly designed for measuring gasolene intesting automobiles. Heretofore it has been common to ascertain thegasolene consumption by measuring the gasolene consumed in some ordinarymeasuring vessel. This is accom-l panied bya great deal of inconvenienceand makes such testing, especially/.if it is carried through anyextendedA range very tedious and in some respects unsatisfactory. Thepresent invention has particularly in view a measuring device in whichthese objections are obviated.

The invention is illustrated in the accompanying drawings as followsFigure 1- is' a plan view of the device.

Fig. 2 a vertical .section of the device on l the line 2-2 in'Fig. 1.

Fig. 3 a section on theline 3-3 in Fig. .2. l marks in outline thecarbureter, 2 a float chamber, 3 a Heat, 4 levers operated by the float,5 a valve'stem, 6 the inlet valve 'to the carbureter, 7 the inletpassage and 8 a connection between the carbureter andthe measuringdevice. The connection 8 isOrdinarily in the form of a. exible tube sothatl the measuring device may be conveniently placed and the fuelcarried from it to the carbureter, the tube extending to the vdischarge9 ofthe measuring device.

The measuring device has a means for supplying fuel to it from aconstant level. As shown `this is accomplished by the float chamber 10.-The ioat 11 in the chamber operates the levers '12. The levers 12operate the valve stem 13 and the valve 14 carried by the stem '13controls the. iniow to the float chamber. This operates in the ordinarymanner of float chambers of. this type.

The inlet opening of the float chamber-15 is connected :by a pipe 16with a supply tank 17, a `pipe 1-8 extending downwardly into the supplytank so that the discharge. from the supply tank may be carried to a'point where the said tank is nearly empty.

The supply tank 17 is inclosed and thev fuel therein is put underpressure by means of an air pump 19, the discharge of the air pump beingconnected through a pipe 20 with the supply tank. By means of this pump'a suicient head may be put' on the liquid in the supply tank throughthe air pressure to elevate the fuel through the pipe 16 to the floatchamber 10. A pressure gage 21 may be supplied so that the pressure maybe observed and the operatorassured of sufficient pressureI to elevatethe liquid to the float.chamber 10.

A discharge projection 22 extends fromv A fitting 23 extends the floatchamber. through an opening 24 in this projection. The fitting has anaxial opening 25- and radial openings 26 connect this axial opening withthe discharge from the oat chamber. An observation tube 27 of glass, orsimilar material, is mounted in the upper end ofthe fitting 23, astuffing box 28 being provided for the lower endof the tube 27.

-A pipe 29 is connected by a union 30 at the lower end of the fitting 23and connects the passage 25 in the fitting with a chamber 31.

the central passage 35 in the fixture 32. Rae,

dial openings 36 extend outwardly from the fitting 35 into a dischargechamber 41 from which the discharge 9 leads. A counteretv head.receptacle is arranged above the chamber 41.l This is preferably formedby means of a glass tube 42 which is arranged in a, stuffing box 43 atthe top of the chamber 41. The tube 42 is concentric with the fitting32. This tube 42 extends upwardly to above the level A-A established bythe float chamber and is in communication with the chamber 41. Theoperation of this measuring device is as follows: When fuel is drawninto the lfloat chamber 2 of the carbureter in the running of theautomombile, this flow of gasolene immediately starts the fiow ofgasolene from the counter-head receptacle 42 and also through therestricted metering opening v 4counter-head receptacle 42 and the levelin the float chamber 10 is such as to create a sufli'cient head at therestricted opening 34 to supply the volumev 'of liquid which is beingdischarged to the carbureter. If this flow remainsv constant the levelof the liquid in the counter-head 42 will remain constant but if thisflow f changes immediately the level in the tube 42 will rise or fall soas to create a difference in level of liquid in it from that ofthe floatchamber 10 to produce the I head necessary to force the volume of liquiddischarged through the restricted opening 34..

It followsLtherefore, that a given flow of liquid will be accompanied bya given level of liquid in 'the tube 42 and itl is only necessary tosupply 'a scale for the tube 42 which will indicate the lowat eachlevel.

In'the present structure a rod 44 is screwed into the tting 32 andlocked therein by a pin 45,. The rod 44 terminates in a button 46 sothat it may be utilized for removing and inserting the fitting 32. Bythis means ttings'having openings 34 of diHe'rent sizesV may beintroduced so as to vary the capacity of the measuring device, One'sideof the rod 44 is flattened as at 47 and a scale 48 is arranged on thisflattened portion having zero at 49. The screw-threaded connection ofthe fitting l32. in the opening 33 may be utilized for vadjusting therod vertically so as to bring zero to the level A-l-'A established bythe float chamber.

In the use of this device in testing with automobiles it is desirable tohave the apparatus so that a supply tank may be sis placed in theautomobile with it and the liquid supplied to the measuring device fromthis tank. -I utilize this tank as a base on which the device ismounted. A pipe 50 is secured. in the tank 17. A second pipe 51 extendsltelescopically into the pipe 50 and has suiiicient length to bring thescale 48 to a suicient elevation to be conveniently read.

A clamp 52 is secured to the upper end of the pipe 51. It has anextension 53 with-a loop or. ring 54 which extends over theupper end'of.the glass tube 42. This forms a guide for the tube and also for thebutton 46 and with it the rod 44. A second clamp 55 is' secured to thepipe 51. It has an extension 56-with a clamp 57 which extends around thefloat chamber 10 and thus supports the upper end of the mechanismsconnected with the float chamber. ber 31 has an extension 37 which has aclamp 38 secured on the pipe-51. The upper end fof the pipe 50 isscrew-threaded at 59 with a tapered screw and is slotted as shown in Thecham 'the tank by means of WhichJthe temperature of the liquid may betaken if desired, this being sometimes a necessary feature of the test.This mercury Well is simply a well open to the atmosphere in whichmercury is placed; The temperature of the gasolene is communicated tothis merc'ury and the temerature ofthe asolene can thus be readilyetermined by te insertion of a thermometer bulb into the mercury well.
